FEED norrnn roncasrnonncnasff I 25 Specification of Letters Patent. II Patented Au-g. 15-, 1922;

Application filed July 30,

To all whom it may concern:

Be it known that I, Gnonen L. RoBINsoN, a citizen of the United States, residing at Beechview, Allegheny County, Pennsyl-, vania, have invented a new and useful Improvement in Feed Hoppers for Gas Pro- .ducers, of which the following is a full,

clear, and exact description, reference being had to the accompanying drawing, forming part of this specification, in which- Figure 1 is a vertical section showing my invention applied to a gas producer, a portion of the gas producer being also shown in vertical section.

Figure 2 is a section on the line Il-II of Figure 1, and

Figure 3 is a section on the line Ill-III of Figure 2.

My invention has relation to feed hoppers for gas producers, and is designed to provide eiiicient/means for cooling those portions of the hopper which are most affected by the heat to which they are subjected in use. In hoppers of this class, considerable difiiculty has been experienced in mainta1n ing a proper seating of the bell which forms the valve controlling the discharge from the body of the hopper intothe. producer, owing to the fact that the bell and its seat become warped by the action of the heat. My nvention provides water-cooled means or simple character for overcoming this trouble, and greatly extends the life of the hopper and bell. I I I Referring to the accompanying drawing in which I have shown a preferred embod1- ment of my invention, the numeral 2 designates a portion of the top of a gas producer having a feed opening 3 surrounded'by the usual water pan 4. 5 designates the'cylindrical body of my improved feed hopper which is preferably formed from sheet ;metal, its upper edge being flanged outwardly, as shown at 6, to seat the cover 7 wardly, as shown at 8, to iorm tne hopper and its lower portion being contracted inproper below the throat ofwhich the metal is again bent outwardly, as shown at 9, to form a seat for the upwardly seating bell 10. The lower edge portion of the metal forming the body of the hopper is flanged outwardly, as shown at 11, to seat upon the flange 12 surrounding the opening 23in. the producer top. I

13 is the outer wall of a water container 1920. serial' No; 400,272

14-whose inner and bottom walls are formed by the lower portion of the hopper body. This wall is suitably secured, as by welding,

to the base flange 11 of the hopper. The top I of the container 14 is closed in any suitable manner as by the angles 15. 16 designates a water inlet pipe, and 17 awater discharge pipe for the container, the latter being shown as discharging into the water pan 4.

18 designates the weighted-lever for actuatmg the bell 10 to which its inner arm is connected by the link 19. To form a support for the fulcrum 20 of this lever, a bracket21 is provided which is bolted or riveted to the body of the hopper, as indicated at 22, this bracket. fitting over the opening 23 in the hopper body through which the lever exstruction is a simple and relatively inex pensive one. I do not wish to limit myself to the particular construction and arrangement which I have ShOWn Sil1Ce it is obvious that the advantages of my invention I canbe obtained, notwithstanding considerv able variations in the details of construction and without departing from the spirit and scope of theappended claims.
